Adderall IR Dosing and Administration

  • The American Academy of Child and Adolescent Psychiatry recommends taking the first dose of Adderall IR 10mg upon awakening in the morning, and the second dose 4-6 hours later, to ensure coverage during school or work hours, with the immediate-release formulation providing approximately 4-6 hours of therapeutic effect per dose 1, 2
  • To minimize sleep-onset difficulties, the American Academy of Child and Adolescent Psychiatry suggests not administering doses after 2:00-3:00 PM 1, 2

Adjusting Dosing for Side Effects

  • If appetite suppression at meals is problematic, the timing of the second dose can be adjusted slightly earlier or later to minimize impact on lunch or dinner, as recommended by the American Academy of Child and Adolescent Psychiatry 1, 2
  • If breakthrough symptoms occur between doses, the American Academy of Child and Adolescent Psychiatry suggests considering dose adjustment or extended-release formulations rather than changing administration times 1, 2
